To all whom z'tmay concern:

"Be it known that I, FIDAVID S. EKENNEDY, a. citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Typographicallt lachines, of Which'the following'is a specification, reference beinghad therein to the accompanying drawing.

My invention relates to typographicalmachines, such aslinotype machinesof the general organization represented in Letters Patent of the UnitedStates to OfMergenthaler, No. 436,532, wherein-circulating matrices arereleased from a magazineinthe 0rder in which their characters are "toappear in print and then assembled in line, thecomposed line transferredto=theface of a mold, the mold filled with molten metal to form a slugor 'linotype against the matrices which produce the type charactersthereon, and the matrices thereafter returned through -a distributingmechanism to the -magazine from Which they started.

In such machines, the release of the matrices from the ma gazin'e isefif'ec'ted by? means of cscap'ements acting through openings in thebottom thereof, and in some instances these escapements areattacheddirectly to the magazine, While in otherinstances theyare'supported independentlythereof. When the escapements arethusindependentlysupported, it becomes'necessary'to lock the matrices in themagazine before it is removed fromthe machine, as otherwise the matriceswould be free'to 'escape therefrom. This is ordinarily insured againstby employing devices which Willpreventthe removal of'the magazineuntilthe matrices have'first been locked therein, such as shown in the U. -S.Patents Nos. 829,868 and 1,101,282 to Thomas S. Humans. In' the first*of the'se patents, in effecting the removal of the magazine, it islifted out of engagement with the escapements. "and the locking-tievices above mentioneclx'serveito prevent the premature raising ofthe'magazin'e; Whilein the second patent,:before themagazine' isremoved. theescapements are lowered out of operative relation thereto,:and the locking devices serve to prevent the movement of theescapements'as distinguished from that of the magazine.

ll [y present invention is intended toproyide devices 'in either classof machine, whereby the locking of the matrices in the magazine iseffected automatically during itsiremoval ancl so as to avoid the delayincidc'nt to the :old practice anc. to relieve the operatorof anyattention on his part. In "the present instance, and as will be fullypointed out later, this automatic locking of the matrices is'controlledby devices which hold the magazine in operative position or in operativerelation to the escapements.

In the accompanying drawings, 1 have shown my invention merely inpreferred formand by Way of example and as applieditothe particularstyle of machine mentioned, 'but obviously many alterations andvariations may be :made therein and in its mode of application, whichwill still be comprised Within its spirit. Thus it may be applied toother forms of typographical 'machines, such as typesetters, and thelike, which handle type or dies instead of matrices. Generally speaking,I desire it to be understood that Ido not limit myself to any specific.form or embodiment, except in so far specified in the claims.

Referring to the drawings:

Figure l is a perspective view of the lower part of a linotype machinewith my invention applied thereto;

Fig. 2 is a vertical section through the lower endoi the magazine andthe escapements, and showing the magazine unlocked and ready forremoval; v

Fig. 3 is a similar view showing the magazine locked in position; and

Fig. 4 is a section on the line of Fig. 3.

The magazine A, Whereinthe matrices X are stored, comprises as usual theside plates A and theedge plates or bars A, the side plates being formedin their inner or opposing faces with the converging grooves 3Aproviding channels for the matrices. As illustrated herein. the magazineis removablv supported in the machine upon the fixed frame which alsogives independent sup port to the escapements C. which pass throughopenings A7 in thebottom plate of the magazine to control the release ofthe matrices therefrom. and are operated from thekeyboard in the usualWay through the vertical reeds C lZn the present instance, therefore,the disengagement of the escapements from the magazine takes place whenthe latter is raised from its supporting frame B for removal, asdistinguished from swinging the escapements out of operative relationthereto, and such disengagement may be prevented by holding or lookingthe magazine in operative position upon the frame. Devices subservingthis purpose are shown herein and comprise a pair of plates D attachedto the opposite edges of the magazine by screws A passing looselythrough fore-and-aft elongated slots D in the plates so as to permitthem to be slid forwardly and backwardly on the magazine. At theirforward ends, the plates D are provided with hooks D to cooperate withpins B projecting inwardly from the opposite sides of the frame 13, thehooks being of such extent that in the forward position of the platesthey engage beneath the pins and prevent the raising of the magazine, asillustrated in Fig. 3, while in the rearward position of the plates,they clear the pins and-permit such raising, as indicated in Fig. 2. Ifdesired, the plates D may be provided with grip pieces D to facilitatetheir movement.

At its upper side the magazine is also provided with a comb plate Earranged to slide vertically between a pair of fixed guide bars A so asto project its teeth E into, or withdraw them from, the magazinechannels. In the lower position of the plate, its teeth stand across orin front of the upper ears of the leading matrices in themagazinechannels, as indicated in Fig. 2, thus preventing their escapetherefrom; and in its upper position, the teeth are withdrawn from themagazine channels or out of the path of the matrices, as shown in Fig.3, thus permitting their escape. The transverse movements of the combplate E are effected by the sliding plates D, the former being providedat its opposite ends with projecting pins E engaging in inclined camslots D in the upper edges of the latter. The slots serve by theircooperation with the pins to raise and lower the comb plate as theplates D are shifted forwardly and backwardly, respectively, they beingplain or straight at the front, as at D*, so as to maintain the combplate depressed when the plates D are in their rearward position. Whenthe plates D are slid rearwardly to disengage the hooks D from the pinsB? and unlock the magazine for removal, the comb plate E is shiftedautomatically to locking position, that is, with its teeth E projectinginto the magazine channels; and when the plates D are slid forwardly tolock or re-lock the magazine in position, the comb plate is shiftedupwardly auto matically to unlocking position or to withdraw its teethfrom the magazine channels. In short, the arrangement is such that thelocking and unlocking of the magazine effects the unlocking and lockingof the matrices therein, respectively.

As shown in Figs. 2 and 3, the rear faces of the teeth E are beveled orinclined as at E so that as they are projected into the magazinechannels by the downward movement of the plate E, they will push thematrices rearwardly a slight distance and thus provide clearance betweenthe matrices and the escapements as the'magazine is reby cam pieces Bprojecting upwardly from the frame 13, but when the magazine is liftedfrom the frame, the pins A are re moved from the control of the campieces and are thus allowed to enter the holes D and lock the plates Dagainst movement. Similarly, when themagazine is replaced upon the frameB, the cam pieces B reengage the pins A and push them out of the holes Dthus releasing the plates D and allowing them to lee-moved forwardly tolock the magazine in place. The efl'ect of this arrangement is that thematrix retaining plate E is automatically looked and unlocked in itsactive position as the magazine is removed from and replaced in themachine, respectively. It will be noted that the inturned flanges D arealso formed with slots D opening into holes 7 to enable Normally thepins A are prevented from entering the holes D them to clear the campiecesB? as the.

plates D are wardly. i

As previously stated, I have shown my improvements merely in preferredform and by way of example, but obviously many changes and modificationswill suggest themselves to those skilled in the art without shiftedforwardly and back departing from the scope of'my invention.
